An investigator was interested in the effects of various treatments on reduction of fear in phobic participants. He suspected that type of phobia may interact with therapeutic treatments; specifically, that the types of treatments for agoraphobics (fear of open spaces) and claustrophobics (fear of closed spaces) might be different. He divided participants into two groups based upon type of fear and then assigned members of each group to treatment groups: exposure therapy, cognitive-behavior therapy, or control (no intervention). After three months of treatment, participants' anxiety in the feared situation was measured. 1. What type of factorial design is the above experiment?

2. How many conditions are in the above experiment?

3. Identify the manipulated variable(s) and levels of each.

4. Is this an IV x PV design? If yes, identify the participant variables.

5. Identify the dependent variable(s).
